SAFETY INFORMTION FOR USERS OF LP-GAS
Propane (LP-Gas) is a flammable gas which can cause fires and
explosions. In its natural state, propane is odorless and colorless.
You may not know all the following safety precautions which can
protect both you and your family from an accident. Read them
carefully now, then review them point by point with the members
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!
• Do not operate electric switches, light matches, use your phone.
Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area. Do
that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-Gas is heavier than air and may settle in low areas such as
basements. When you have reason to suspect a gas leak, keep
out of basements and other low areas. Stay out until firefighters
declare them to be safe.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must find out if you
can smell the odorant in propane. Smoking can decrease your
ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors
in the area mask the gas odor. People may not smell the gas odor
or their minds are on something else. Thinking about smelling a
gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can filter the odorant. Odorants
of your household. Someday when there may not be a minute to
lose, everyone's safety will depend on knowing exactly what to
do. If, after reading the following information, you feel you still
need more information, please contact your gas supplier.
• Use your neighbor's phone and call a trained LP-Gas service
person and the fire department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and firefighters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
in LP-Gas also are subject to oxidation. This fading can occur if
there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into walls,
masonry and other materials and fabrics in a room. That will take
some of the odorant out of the gas, reducing its odor intensity.
LP-Gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels. Always be sensitive to the slightest gas
odor. If you detect any odor, treat it as a serious leak. Immediately
go into action as instructed earlier.
SOME POINTS TO REMEMBER
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it to
find out what the propane odor smells like. If you suspect that
your LP-Gas has a weak or abnormal odor, call your LP-Gas
Dealer.
• If you are not qualified, do not light pilot lights, perform service,
or make adjustments to appliances on the LP-Gas system. If
you are qualified, consciously think about the odor of LP-Gas
prior to and while lighting pilot lights or performing service
or making adjustments.
• Sometimes a basement or a closed-up house has a musty smell
that can cover up the LP-Gas odor. Do not try to light pilot
lights, perform service, or make adjustments in an area where
the conditions are such that you may not detect the odor if
there has been a leak of LP-Gas.
• Odor fade, due to oxidation by rust or adsorption on walls of
new cylinders and tanks, is possible. Therefore, people should
be particularly alert and careful when new tanks or cylinders
are placed in service. Odor fade can occur in new tanks, or
Page 4
reinstalled old tanks, if they are filled and allowed to set too
long before refilling. Cylinders and tanks which have been out
of service for a time may develop internal rust which will cause
odor fade. If such conditions are suspected to exist, a periodic
sniff test of the gas is advisable. If you have any question about
the gas odor, call your
the LP-gas is a good safety measure under any condition.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
• If you experience a complete "gas out," (the container is under
no vapor pressure), turn the tank valve off immediately. If the
container valve is left on, the container may draw in some air
through openings such as pilot light orifices. If this occurs,
some new internal rusting could occur. If the valve is left
open, then treat the container as a new tank. Always be sure
your container is under vapor pressure by turning it off at the
container before it goes completely empty or having it refilled
before it is completely empty.

the rating plate is the responsibility of the person and company
making the change.
Important
All correspondence should refer to complete Model Number, Serial
Number and type of gas.
Notice: During initial firing of this unit, oil from the heat exchanger
may bake out and smoke may occur. To prevent triggering of smoke
alarms, ventilate the room in which the unit is installed.
Installation in Residential Garages
Gas utilization equipment in residential garages shall be installed
so that all burners and burner ignition devices are located not less
than 18" (457mm) above the floor.
Such equipment shall be located, or protected, so it is not subject
to physical damage by a moving vehicle.
Qualified Installing Agency
Installation and replacement of gas piping, gas utilization equipment
or accessories and repair and servicing of equipment shall be
performed only by a qualified agency. The term "qualified agency"
means any individual, firm, corporation or company which either in
person or through a representative is engaged in and is responsible
for (a) the installation or replacement of gas piping or (b) the
connection, installation, repair or servicing of equipment, who is
